At.In conjunction with the content of above-described embodiment one, method provided in this embodiment is illustrated.Referring to fig. 2, the present embodiment mentions
The method flow of confession includes:
201: determining that at least one data acquisition instructs according to configuration file, configuration file is used for depositing in first database
The attribute of each column data under the every tables of data and every tables of data of storage is described；
Configuration file can include but is not limited to that label language can be expanded for XML(eXtensible Markup Language
Speech) type file, the present embodiment do not make specific limit to the type of configuration file.
For example, may include every tables of data and every by taking configuration file is the file of XML type as an example, in XML file
The relevant attribute of each column data under tables of data, such as mark of every tables of data and each column under title, every tables of data
The mark and title of data, the major key title of every tables of data determine the prefix of every tables of data that needs are used when key assignments etc..
It certainly, can also other type categories comprising tables of data and each column data under tables of data in configuration file
Property, the present embodiment does not make specific limit to the content for including in configuration file.
Since subsequent needs are from the first data obtained under every tables of data in first database, therefore, it is necessary to first bases
Configuration file determines that data acquisition instructs.Wherein, the format of data acquisition instruction is related with the type of first database, for example,
If first database is relevant database, data acquisition instruction at this time can be Select case statement.Again due to every
The corresponding data instruction of tables of data, therefore, the data acquisition instruction determined according to configuration file is at least one.The present embodiment
Do not determine that the mode of data acquisition instruction specifically limits to according to configuration file, including but not limited to: true according to configuration file
The title of the fixed each column data of every tables of data, and determine the mode for obtaining data simultaneously, according to the title of each column data with
And the mode of acquisition data determines the corresponding data acquisition instruction of every tables of data.
For example, one four column datas are shared in an existing tables of data, the entitled t_app_info_new of the tables of data,
In, the corresponding entitled app_id of the first column data, the i.e. column data are used to indicate the corresponding id of different application, the second column data
Corresponding entitled app_name, the i.e. column data are used to indicate the title of different application, and third column data is corresponding entitled
App_creat_name, the i.e. column data are used to indicate the creation time of the corresponding data of different application, and the 4th column data is corresponding
Entitled app_updata_name, i.e. renewal time of the corresponding data of different application.It is shared in the tables of data one
For 10000 datas, however, it is determined that the mode for obtaining data is by 10000 datas in tables of data according in every data
App_id numerical value ascending order arrangement after obtained, and obtain be in ascending sort result the 1st article to the 500th article this 500
Data, at this point, the data acquisition instruction is expressed as follows with Select sentence in relevant database:
Select app_id, app_name, app_creat_name, app_updata_name from t_app_
Info_new order by app_id limit0,500
Wherein, order by app_id clause representation will be every in tables of data t_app_info_new in Select sentence
Data carries out ascending order arrangement according to the numerical value of app_id in every data, has two parameters, first item parameter in limit clause
Indicate that the offset of first returned data, Section 2 parameter indicate the maximum number of the total number of returned data.Due to above-mentioned
The value of first item parameter and Section 2 parameter is respectively 0 and 500 in limit clause in Select sentence, according to first item parameter
Value can determine first returned data be ascending sort result in the first data, can determine according to the value of Section 2 parameter
The maximum number of the total number of returned data is 500, and therefore, the data finally obtained are just the 1st article in ascending order rank results
To the 500th article of this 500 data.
In addition, can be obtained altogether when the value of first item parameter in limit clause and Section 2 parameter is respectively 0 and 500
To 500 datas, being equivalent to Select sentence of execution just can get 500 datas.If next time also needs to obtain subsequent
500 datas, at this point, the numerical value of first item parameter in limit clause can be become 500 plus 500, by the number of Section 2 parameter
It is constant that value remains 500, to can at most obtain 500 datas again.According to the method described above, each batch at most obtains 500
Data can get data all in tables of data after a point several batches obtain data.
The corresponding Select sentence of every tables of data may finally be determined in above manner, i.e. every tables of data is corresponding
Data acquisition instruction.
202: according to every data acquisition instruction from obtained in first database under every tables of data at least one the first
Data；
The present embodiment not to according to every data acquisition instruction from being obtained in first database under every tables of data at least
The mode of one the first data specifically limits, including but not limited to: according to the side for obtaining data in every data acquisition instruction
The first data of formula and the name acquiring every of each column data.
For example, Select sentence is selection when illustrating in step 201 so that data acquisition instruction is Select sentence as an example
Sentence, tables of data when obtaining data are as shown in table 1.
Table 1
| app_id | app_name | app_create_time | app_update_time |
| Id1 | Name1 | Creat_time1 | Updata_time1 |
| Id2 | Name2 | Creat_time2 | Updata_time2 |
At this point, due to only having two datas in table 1, the data that Select sentence is got are two the first data,
It is respectively as follows:
First the first data: Id1, Name1, Creat_time1, Updata_time1
The first data of Article 2: Id2, Name2, Creat_time2, Updata_time2
It should be noted that is actually obtained due to Select sentence is the 1st article to the 500th article in ascending sort result
This 500 data, at this point, if in table 1 the item number of data it is unlimited above two, the item number of data is relatively more, if any 10000
Data then can obtain 500 datas according to the process in step 201.
203: determining the corresponding key assignments of every first data and corresponding second data of every first data, the second data
It is made of the quantity of non vacuum data in the first data and the first data；
The present embodiment does not limit the mode of the corresponding key assignments of every first data of determination specifically, including but not limited to:
It determines the corresponding tables of data of every first data, and determines prefix and every tables of data of the every tables of data in configuration file
The major key column data that includes title；The title for the column data that major key according to every tables of data includes determines every first number
According to the corresponding value of major key；The corresponding value of major key of the prefix and every first data of every tables of data is combined, from
And determine the corresponding key assignments of every first data.
For example, first data are first the first data instance in step 202 using tables of data as table 1.If table 1 is being matched
Setting prefix in file is appinfo, entitled one of the column data that the major key of table 1 includes, and be app_id, then first
The corresponding value of the major key of first data is Id1.At this point, the prefix appinfo by table 1 is corresponding with the major key of first the first data
Value be combined for Id1, it may be determined that the corresponding key assignments of first the first data be appinfo_Id1.
The present embodiment does not also limit the mode of corresponding second data of every first data of determination specifically, including but not
It is limited to: determines the quantity of non vacuum data in every first data；Each non vacuum data in every first data is converted to correspondence
TLV(Type/Length/Value, type/length/value) formatted data；By the quantity of non vacuum data in every first data
TLV formatted data corresponding with non vacuum data each in every first data is combined, so that it is determined that every first data pair
The second data answered.
For example, using the first data as first the first data instance in step 202.If Id1, Name1, Creat_
Tetra- data of time1, Updata_time1 have value, i.e., four data are all non-empty, at this time, it may be determined that first the first data
The quantity of middle non vacuum data is 4.If Updata_ in tetra- data of Id1, Name1, Creat_time1, Updata_time1
The value of time1 is sky, can determine that the quantity of non vacuum data in first the first data is 3 at this time.
Non vacuum data in four data is separately converted to corresponding TLV formatted data, by taking Creat_time1 as an example,
The data are identified as 3, length 10, numerical value 14-04-08, at this point, can turn each item data in TLV formatted data
Corresponding binary data is turned to, it is corresponding that data Creat_time1 can be obtained in binary data sequential connection after conversion
TLV formatted data.The corresponding TLV formatted data of available four data in above manner, then first first is counted
It is converted into binary data according to the quantity of middle non vacuum data, and TLV formatted data corresponding with four data is linked in sequence
Obtain corresponding second data of first the first data.
204: the corresponding key assignments of every first data the second data corresponding with every first data being stored, are obtained
Second database；
When being stored, the corresponding key assignments of every first data the second data corresponding with every first data are opposite
Answer, i.e. every data is made of key assignments and corresponding second data in the second database, the key assignments in every data with it is corresponding
Second data match.
Wherein, the second database can be Key-Value distributed memory system, such as redis storage system,
Memcached storage system, can according to need in practical operation and selects different storage systems, and the present embodiment does not make this to have
Body limits.Second database can store in the shared drive of service server, and the present embodiment is also not especially limited this.
Since the second database is using Key-Value distributed memory system, i.e. NoSQL non-relational database,
To eliminate the relationship type characteristic in traditional Relational DataBase, so that the second database is very easy to extension.In addition, benefiting
In irrelevant property, simple second database of structure can also have very high readwrite performance, especially under big data quantity, energy
Enough there is preferable performance.
It should be noted that realization process all in step 201 to step 204 in actual operation can be by being pre-created
Finger daemon execute, finger daemon is detached from server and in the process of running background, and disengaging can in server
The information of finger daemon in the process of implementation is avoided to show on any server, while finger daemon will not be by any service
Server info caused by device is interrupted.Can be completed according to the realization process of step 201 to step 204 by finger daemon
The one database process that data full dose loads into the second database, i.e., convert second for data all in first database
Data in database.
Due to storing the corresponding key assignments of every first data the second data corresponding with every first data, obtain
After second database, it is also possible to it needs to be updated the second data stored in the second database, it is existing according to the actual situation
Renewal process is divided into two ways, is illustrated in detail as follows:
The first update mode: every the tables of data in preset time detection first database with the presence or absence of increase data；
If detecting the presence of the tables of data for increasing data, the corresponding data of tables of data of every increase data are determined according to configuration file
Acquisition instruction；At least one increased first number under the tables of data of every increase data is obtained according to every data acquisition instruction
According to；Determine that the corresponding key assignments of increased first data of every got and every increased first data corresponding second count
According to；The corresponding key assignments of every increased first data the second data corresponding with every increased first data are stored,
The second database updated.
The present embodiment is not to every the side in preset time detection first database with the presence or absence of the tables of data for increasing data
Formula makees specific restriction, including but not limited to: the tables of data in first database being divided into two kinds in advance, the first is to need increment
The tables of data that the tables of data of load, i.e. data will increase when updating, second is the tables of data for not needing step increment method, i.e. data
It will not increased tables of data when update.Every needs the tables of data of step increment method after increasing a data, can be by the first data
Every needs the dwOldUpdateTime of the tables of data of step increment method current renewal time to be recorded in library, and records simultaneously
The dwNewUpdateTime final updating time of every tables of data for needing step increment method.Wherein, every needs step increment method
For tables of data after increasing a data, every needs the dwOldUpdateTime of the tables of data of step increment method to need to increase with every
The dwOldUpdateTime for measuring every first data in the tables of data of load is identical, every tables of data for needing step increment method
DwNewUpdateTime needs the dwNewUpdateTime of every first data in the tables of data of step increment method identical with every.
In addition, every needs the tables of data of step increment method after increasing a data, dwOldUpdateTime with
DwNewUpdateTime be it is identical, when in the tables of data that every needs step increment method the first data increase when, every needs
The dwNewUpdateTime of the tables of data of step increment method can just change.Based on the above principles, it can be examined every preset time
Survey every tables of data for needing step increment method in first database dwOldUpdateTime and dwNewUpdateTime whether
It is identical, if the two is different, it can determine all tables of data for increasing data.Wherein, preset time can carry out according to demand
Setting, the present embodiment make specific limit to the value of this preset time.
Since every needs the tables of data of step increment method after increasing a data, every needs the tables of data of step increment method
In every first data dwOldUpdateTime need step increment method with every tables of data in every first data
DwNewUpdateTime is identical, only when the first data in tables of data increase, first data
DwNewUpdateTime can just change, and cause different from dwOldUpdateTime.Therefore, when determining all increase data
Tables of data after, can more every increase data tables of data in every first data dwOldUpdateTime with
Whether dwNewUpdateTime is identical, if the two is different, can determine all the first data for increasing data.
It determines in tables of data that every needs step increment method after all the first data for increasing data, it can be further according to configuration
File determines the corresponding data acquisition instruction of the tables of data of every increase data, obtains every increasing according to every data acquisition instruction
At least one increased first data under the tables of data of addend evidence determine that every increased first data got are corresponding
Key assignments and corresponding second data of every increased first data, to the corresponding key assignments of every increased first data and every
Corresponding second data of increased first data are stored, the second database updated.Pass through the first update mode
In method and step can complete first database into the second database data increment load process, i.e., by first database
In all increased data be converted into the data in the second database.It should be noted that the realization of above-mentioned step increment method
Journey can be with reference to the process that data full dose loads into the second database of first database in above-mentioned steps, and details are not described herein again.
In addition, the process of step increment method can also be executed by finger daemon, the present embodiment is not especially limited this.
Wherein, it completes to increase according to the testing result in above-mentioned detection first database with the presence or absence of the tables of data for increasing data
After the process for measuring load, the dwOldUpdateTime and every need of the tables of data that every needs step increment method can also be updated
The dwOldUpdateTime for wanting every first data in the tables of data of step increment method allows it with corresponding dwNewUpdateTime
It is consistent, in order to which next time is detected.
In addition, in order to guarantee that data can be constantly in last state, the case where preventing step increment method from failing, can also set
Set an incremental count value cnt, wherein the initial value of cnt is 0.When carrying out step increment method every time, it can determine whether that the value of cnt is
It is no to be greater than preset threshold.If the value of cnt is less than preset threshold, continue the mistake of step increment method according to the method for above-mentioned steps
Journey, and after step increment method, the value of cnt is added 1.If the value of cnt is greater than preset threshold, directly according to above-mentioned steps
Method carries out the process of full dose load, and after full dose load, the value of cnt is set to 0 again.Wherein, preset threshold
Value can be selected according to actual needs, and the present embodiment is not especially limited this.
Second of update mode: asynchronous notifications request is obtained；Determine that data obtain according to asynchronous notifications request and configuration file
Instruction fetch；Modified first data are obtained from first database according to data acquisition instruction；Determine modified first number
According to corresponding second data, modified second data are obtained；The second data before the replacement of modified second data is modified,
The second database updated.
After user has modified the first data stored in first database by the management backstage in terminal, can from terminal to
The service server for storing first database sends asynchronous notifications request, wherein includes the first data in asynchronous notifications request
The relevant information for the first data modified in library can determine that data acquisition refers to according to asynchronous notifications request and configuration file
It enables.
For example, asynchronous notifications request can be made of following three information: tables of data locating for the first data modified
TLV formatted data corresponding to the major key of mark, the number of major key and the first data modified.
The title that can determine tables of data by the mark of tables of data locating for the first data for being modified, can according to configuration file
The title for determining all column datas in the tables of data, by corresponding to the number of major key and the major key for the first data modified
TLV formatted data can determine the major key for the first data modified, thus can determine data acquisition instruct.With the name of tables of data
Referred to as t_app_info_new, for the major key for the first data modified is Id1, at this point, relationship is used in data acquisition instruction
Select sentence is expressed as follows in type database:
Select app_id, app_name, app_creat_name, app_updata_name from t_app_
info_new where app_id=Id1
After determining data acquisition instruction, it can be instructed according to data acquisition and obtain modified first number from first database
According to determining corresponding second data of modified first data, obtain modified second data, by modified second data
The second data before replacement modification, the second database updated.Wherein it is determined that the realization process after data acquisition instruction can
With with reference to the content in above-mentioned steps, details are not described herein again.
In addition, when due to obtaining the data in first database, needing to be obtained according to data during above-mentioned all realizations
Instruction fetch is obtained, and data acquisition instruction needs to be determined according to configuration file, and the definition of configuration file may be because
The modification of user and change.Therefore, the case where being modified for above-mentioned configuration file determines at least according to configuration file
After one data acquisition instruction, configuration file amendment advice can be obtained, is obtained according to configuration file amendment advice modified
Configuration file.When determining data acquisition instruction according to configuration file next time, number can be determined according to modified configuration file
According to acquisition instruction.
For example, when the definition of configuration file is changed due to the modification of user.At this point, can be from server to guarding
Process sends signal, i.e. configuration file amendment advice.It, can be to for example, if what is installed on server is the system of Linux class
Finger daemon sends Linux SIGUSR1 signal.Finger daemon can obtain modification after receiving Linux SIGUSR1 signal
Configuration file afterwards, according to the data storage operations of modified configuration file triggering next time.Data next time store behaviour
It needs to determine that at least one data acquisition is instructed according to modified configuration file, and then triggers to execute and be referred to according to data acquisition
The subsequent step from at least one the first data obtained under every tables of data in first database is enabled, detailed process is the same as this number
Consistent according to storage operating principle, details are not described herein again.
It should be noted that the modification of configuration file can be based on table level, it can also be based on column grade.Due to configuration file
It is mainly used for carrying out the attribute of each column data under the every tables of data and every tables of data stored in first database
Description, therefore, when having newly increased a tables of data in first database, can be added in configuration file and increase data newly to this
The description of Table Properties.It, can be in configuration file to the data when having modified the attribute of a tables of data in first database
